Effects of Reiki, Yoga, or Meditation on the Physical and Psychological Symptoms of Chemotherapy-Induced Peripheral Neuropathy: A Randomized Pilot Study

Three complementary approaches for managing physical and psychological symptoms related to chemotherapy-induced peripheral neuropathy were evaluated against an education-only control arm. This study included 26 participants who were randomly assigned to weekly, hour-long sessions of yoga, Reiki, meditation, or an educational control experience for 6 weeks. Each participant completed pre-post measures of neurotoxicity, quality of life, psychological distress, and mindfulness. Descriptive analysis of the data indicated that all experimental group participants demonstrated improved within-group scores on quality of life and neurotoxicity outcomes following intervention; however, the improvements were not statistically significant. Neurotoxicity worsened significantly in the control group, but there were no pre-post changes with respect to quality of life, psychological distress, or mindfulness. Effect sizes were large with respect to meditation and mindfulness and with Reiki and psychological distress. Moderate effect sizes with respect to yoga and neurotoxicity and quality of life offer promise for all 3 interventions in managing chemotherapy-induced peripheral neuropathy.
